But a couple of hours ago, the insider says, a confrontation occurred between Bieber's entourage and club security, prompting Bieber's entire party to leave. The entire incident went down very quickly and they headed straight back to their hotel afterward, the source adds.

Twitter, meanwhile, is abuzz with disappointed fans using the hashtag "#BeliebersHatePaparazzi" and blaming photographers for ruining the Biebs' big day.
